My encoder based focuser

So after I built a focuser controlled by a joystick, and considered it a usability failure, I built one based on an encoder, and modified the soapbox accordingly, maintaining backward compatibility.

Below is the block diagram, explaining how it optionally fits into the soapbox daisy chain. Most variables are hand tuned for the DC motor + reductor gear box in use, as the source code reveals.

Jól kalibrált monitoron mindegyik számnál elkülönülő árnyalat látszik. Ha mégsem látszanak, akkor a megjelenített képek színhiányosan rajzolódnak ki. A monitort valószínűleg kalibrálni kell.

You should see distinct shades for each number. If those shades are not clearly visible, the displayed pictures will lack accuracy. Your display most likely needs to be calibrated (brightness, gamma, contrast etc.).
